He said: "Kerrin is a real professional and a great asset to the team. He is a super pilot with a lot of finesse and is very sensitive with the two-year-olds and doesn't knock them about.

"The whole stable likes Byron. I think he suffered from the 'bounce' factor when he ran in the St James's Palace Stakes at Royal Ascot after his huge run in the French Guineas.

"He's not very big, but he's all heart."

Mick Channon was beaming from ear to ear after Tournedos came from last to first to land the Betfair Molecomb Stakes by a neck from Mary Read.

Ted Durcan looked to be in trouble but extricated Tournedos (14-1) and swooped on the wide outside to snatch the Group Three contest in the final couple of strides.

Channon said: "Tournedos had no chance in the Super Sprint at Newbury because he was drawn in the wide open and is a horse who wants cover.

"They looked to have gone too fast and we needed luck in running - and for once it happened.

"There are not a million options open for him because if he goes to York he will have a penalty and it won't be easy, and after that we would be looking at the Flying Childers Stakes at Doncaster."

Sir Mark Prescott is enjoying a productive July and his Coat Of Honour (10-1) took the Sterling Insurance Summer Stakes by a neck and half a length from Impeller and Bonecrusher.

The Seb Sanders-ridden four-year-old found extra when challenged inside the final furlong despite wandering about, while the third home was flying at the finish.

Sanders said: "Today was the first time he'd been in front without blinkers and it was like riding a two-year-old."

Mephisto advertised his totesport Ebor claims with a dramatic victory in the Tatler Summer Season Stakes.

Darryll Holland had nowhere to go when he found himself trapped on the rails over a furlong out on Luca Cumani's five-year-old, but once the gap appeared the 7-2 favourite sprinted through to beat Sergeant Cecil by half a length.

The winner has picked up a 7lb penalty for the Ebor, and Cumani said: "He was a little bit squeezed on the bend and in the straight. I thought he might struggle, but thankfully they didn't go very fast and the gaps appeared."

Mephisto's stable companion Alkaased, who runs in the Listed Glorious Stakes on Friday, is also strongly fancied for the Ebor.

Cumani added: "We'll see how the other runs and then make decisions. But there isn't much else for this one, so he'll probably go to York, penalty and all."
